I took our former 5vr to a tire dealer but wasn't thrilled to see that they jacked it up completely on one side in order to change both tires at the same time. At the same time they were changing the brakes which I supplied to them so it was up that way for quite a while. We just changed tires on our present one and even though we used the same shop we jacked up on tire at a time and took it to the shop to be replaced. The shop is 7 miles from our home so it wasn't a big inconvenience but the peace of mind was worth it. Brakes looked good so didn't bother with them. Either way you decide to do it you should be present during the jacking process to insure they do it correctly. When the guy started to jack up the former one he placed his jacks under the axle. I immediately stopped him and had the move them under the U-bolt and springs. Could have been a disaster if he had bent an axle. He had never worked on a trailer that large before so it was a learning experience for him and he thanked me for my info. Good luck to you and happy RV'ing.
